Adenovirus-Associated Urethritis, a Not So Uncommon Entity. A Review of 91 Cases

First-void urine samples showed significantly higher detection rates of HPV-specific IgG antibodies compared to midstream urine, confirming the necessity of capturing the initial stream. The study found no significant difference between 10 mL and 20 mL collection volumes, indicating flexibility in device specifications for self-collection.

The bivalent HPV vaccine showed 100 percent effectiveness against vaccine types 16 and 18 seven years post-vaccination in Thai schoolgirls, but only 32.8 percent effectiveness against other high-risk types, indicating limited cross-protection. The study used first-void urine self-collection for HPV DNA detection, demonstrating a scalable, non-invasive approach for vaccine effectiveness monitoring in decentralised settings.

The study found comparable seropositivity for Chlamydia trachomatis and Toxoplasma gondii among male partners of infertile couples in Odisha, with 28 per cent showing anti-Chlamydia IgA and 28 per cent anti-Toxoplasma IgM antibodies. This demonstrates that first-void urine and seminal fluid can detect relevant infections, supporting their use in decentralised fertility screening programmes.

First-void urine sampling detected Mycoplasma genitalium in 8% of 493 men with non-gonococcal urethritis at a Hong Kong STI clinic. With antimicrobial-resistance mutations in 63% of isolates, including dual-class resistance in 37%, the results support decentralised screening to guide therapy.
